KNITTING-MACHINE NEEDLE.

Application filed May 25, 1927.

My invent-ion relates more particularly to that class of knittingmachine needles in which the latch and the hooked part of the needle aremovable relatively to each other, and preferably the latch is aslidinglatch in guided sliding relation to the hooked part ot the needle, whichdraws the new loop.

The main object of my invention is to construct the needle so that thesliding latch will always close properly and facilitate the casting ofthe old loop.

In the accompanying drawings:

Fig. 1 is a side elevation to an enlarged scale of a knitting machineneedle construct- 7 ed in accordance with my invention and adapted foruse in circular or straight knitting machines;

Fig. 2 is a similar side view showing the sliding latch projected to thecasting oil position;

Fig. 3 is a perspective view of the sliding latch;

i -i is an edge view of the closed latch,

ionding with Fig. 2;

F 5 is atransverse section on the line 5 of Fig. 1.

This takes the place of my application Ser. No. 636,082 filed May 2,1923.

The hooked part- A01 thelneedle, which has at its outer end the usualhook a for taking the yarn and drawing the new loop may be o t anysuitable construction and by pretercnce, it has at its rear end asuitable butt A by which the knitting cams may cause the necessaryreciprocation of the needle.

On the side of the shank toward the hook of the needle is formed alongitudinal groove 10 adapted to receive and guide the toe 12 of thesliding latch 13. The outer end of this groove 10 is canimed out asindicated at 1 l. in Figs. 1 and 2, to cause the point 12 of the slidinglatch B, when fully projected, to more outwardly to meet the point ofthe hook (I.

The rear end of this sliding latch may be n'ovided with a butt B to beoperated by a cam or cams on the machine, or it may be actuated in anyother convenient way.

I prefer to limit the longitudinal move ments of the latch B withrelation to the needle part A by providing a projection 13 on the latchto contact with shoulders 14: and 15 on the part A at the extremities ofthe relative movements of the two parts of the needle.

Serial No. 194,223.

One of the most im iortant features of my invention consists in makingthe outer end of the point of the latch split through to embrace betweenthose split ends the point of the hook a. As the best way to accomplishthis I make the sliding latch of a pair or thin plates 16, 16, closelysecured together by rivets 1'7, 17, or in any other suitable way, and Ithin down the point 12 of the sliding latch at the side next the shankof the needle A as seen in Figs. 3 and 5, so that it may convenientlyenter and be guided within the groove 10, as before explained. The partsof the two plates 16, 16 constituting the point oi the sliding latch areso constructed as to tend to spring apart slightly, as seen in Fig. 3,when they come out of the groove 10. Thus the split point of the latchis collapsible, or closes up, when drawn back into the groove in theshank of the needle and can consequently be then buried in that groovewhile on the other hand the split point of the sliding latch expandslaterally when it is projected out of the groove to em brace and burythe point of the hook a. I also prefer to make the rear ends of theplates 16, 16, spring apart slightly so as to provide a frictionalbearing against the side walls of the needle grooves of the cylinder,dial or frame of the machine, as the case may be.

The groove 10 in the shank of the part A is preferably deep enough tosubstantially cover the point 12 of the sliding latch B, when the latteris drawn back, as seen in Fig. 1. And this is preferably true for thefull length of the groove so that when the instep needles in a hosieryknitting machine are projected to inoperative positions during theknitting of the heel and toe pockets, the points of the sliding latchesB may be reciprocated within the loops on the shanks of the parts Awithout harm,

IVhat I claim is:

1. A knitting machine needle having a hooked part with a grooved shank,in com bination with a relatively movable latch having an endsplit-through permitting the two sides of the end to yield and embracethe point of the hook when projected, said end being adapted to slide inthe groove of the shank.

2. A knitting machine needle having a. hooked part, in combination witha relatively movable latch having an end splitthrough permitting thepoint of the latch to expand laterally and embrace the point of the hookwhen the latch is projected.

3. A knitting machine needle having a p hooked part with a groovedshank, in combination with a sliding latch constructed of two platesclosely secured together, the point of the latch being adapted to slidein the groove of the shank of thehooked part and to resiliently yieldand embrace the point of the hook when projected.

4. A knitting machine needle having a hooked part with a grooved shank,in combination with a sliding latch constructed of two plates, the pointof the latchbeing resilient and the two plates being adapted to yieldlaterally and embracethc point of the hook when thelatch .is projected,the side of the latch adjacent the shank being reduced in width to enterthe grove in the shank.

A knitting machine needle having a hooked part, in combination with asliding latch constructed of two plates riveted together with theforward and rear ends rcsilient said forward end being adapted to yieldlaterally and embrace the point of the hook when the latch is projected,as and for the purposes set forth.

6. A, knitting machine needle having a hooked part with a grooved shank,in com bination with a relatively movable latch having a resilientsplit-through end which when projected will yield and embrace the ointof the hook and when retracted will be wholly contained within thegroove of the shank.

'Z. A knitting machine needle having a hooked part with a grooved shankcammed out at the outer-end, in combination with a relatively movablelatch having a resilient split-through end which when projected willbelcalnmed outwardly and yield and cmbrace the point of the hook andwhen retracted will be wholly contained within the groove of the shank.

8; A knitting machine needle having a hooked part with a grooved shank,in combination with a sliding latch constructed of two plates rivetedtogether, the parts of the two plates forming the point of the latchbeing adapted upon retraction to be compressed within and to be coveredby the groove in the shank but adapted when projected to be pushedupwardly toward'the point of the hook, to expand laterally and toembrace the point of the hook, substantially as described.

In testimony whereof I have signed my name to this specification.
